Hauv qab no yog ob peb yam sib xyaw ua ke ntawm ABS
ABS / PVC Blending Hloov Kho
Qhov kev ua tau zoo ntawm ABS / PVC co-blends yog cuam tshuam los ntawm ntau yam, nrog rau kev sib raug zoo thiab muaj pes tsawg leeg ntawm ob lub resins yog qhov tseem ceeb. Polyvinyl chloride tuaj yeem ua rau kom cov pa ntsuas ntawm ABS mus rau 28.5, thiab Sb2O3 thiab halogenated nplaim retardants feem ntau siv. Cov nplaim hluav taws kub hnyiab tau cuam tshuam rau qhov cuam tshuam lub zog ntawm ABS / PVC systems. Kev siv Sb2O3 ib leeg tuaj yeem ua si qhov siab tshaj plaws ntawm cov nplaim hluav taws, tab sis qhov cuam tshuam lub zog ntawm lub cev poob ntau dhau, yuav tsum tsis tshua tsim nyog, thiab halogenated nplaim retardants thiab antimony nplaim retardants muaj kev sib koom ua ke, tuaj yeem txo tus nqi thermal. decomposition cov tshuaj tiv thaiv ntawm cov resin kom ua tiav cov nyhuv ntawm cov nplaim hluav taws, thiab lub kaw lus tsis tshua muaj kev cuam tshuam rau kev ua haujlwm. Yog li ntawd, kev siv cov nplaim hluav taws sib txuas hauv ABS / PVC system yog qhov kev xaiv zoo dua.
ABS / PC sib xyaw hloov kho
Polycarbonate (PC) yog ib qho kev ua tau zoo ntawm cov thermoplastic engineering yas, nrog cov khoom siv zoo heev, qhov ruaj khov, kub thiab txias tsis kam, siab cuam tshuam lub zog, dav siv hauv hluav taws xob, khoom siv hluav taws xob thiab kev tsim tsheb. Txawm li cas los xij, vim lub siab melting point ntawm polycarbonate, ua haujlwm tsis zoo, cov khoom lag luam yooj yim rau kev ntxhov siab tawg, muaj zog rhiab heev rau qhov sib txawv, tus nqi kuj yog siab heev, yog li txwv tsis pub siv polycarbonate rau qee yam.
ABS resin thiab PC sib xyaw, txhim kho cov cua sov ua haujlwm thiab cov khoom siv hluav taws xob ntawm ABS, ntawm qhov tod tes, txo tus nqi ntawm PC thiab yaj viscosity, txhim kho fluidity, tuaj yeem txhim kho nws cov txheej txheem, txo cov kev ntxhov siab sab hauv thiab cuam tshuam lub zog ntawm cov khoom. Lub thickness ntawm cov khoom ntawm rhiab heev, qhov tshwm sim co-mingled kub kev ua tau zoo ntawm ABS thiab PC, ob qho tib si muaj kev cuam tshuam lub zog, flexural, rigidity thiab kub tsis kam, tab sis kuj muaj cov khoom ua haujlwm zoo, thiab txhim kho tshuaj tiv thaiv thiab tsis tshua muaj kub toughness. , kub distortion kub tuaj yeem siab dua li ABS 10 degree los yog li ntawd, thaum tus nqi nruab nrab, yog li txoj kev loj hlob sai heev.
ABS / PA sib xyaw hloov kho
Polyamide (PA) yog siv dav hauv tshuab, twj, tsheb, khoom siv hluav taws xob, ntim khoom thiab lwm yam kev lag luam yas, nrog cov tawv tawv, hnav-tiv taus, hnyav-resistant, roj-resistant, ntau yam kub ({{3}) } ~ 100 degree ) thiab cov viscosity qis, thiab lwm yam, tab sis kuj tseem muaj cov dej nqus dej loj, qhov ruaj khov ntawm qhov tsis zoo, tsis tshua muaj kub thiab tsis tshua muaj zog ntawm lub xeev qhuav thiab lwm yam tsis txaus, uas txwv nws daim ntawv thov.
ABS thiab PA sib xyaw ABS / PA alloy nrog lub toughness ntawm ABS, nyob rau hauv tam sim no dav siv engineering cov ntaub ntawv, ABS thiab polyamide blends yog ib qho ntawm cov ntaub ntawv uas muaj lub zog siab tshaj plaws. Nws yog ib qho kev sib xyaw ntawm amorphous thiab crystalline polymers uas txhim kho cov tshuaj lom neeg ruaj khov ntawm ABS ntawm qhov kub thiab txias thiab muab kev tiv thaiv warping, zoo txaus thiab zoo tsos.
ABS / PET Blend Hloov Kho
Polybutylene terephthalate (PET) yog linear polyester thiab thermoplastic engineering yas. Nws yog tshwj xeeb tshaj yog haum rau iav fiber reinforcement, ua rau cov ntaub ntawv muaj zog nrog txhua yam muaj zog tshaj li ntawm polyphenylene ether (PPO), polyoxymethylene (POM) thiab polycarbonate (PC).
Kev sib xyaw ntawm ABS resin nrog PET yog ib feem ntawm kev ua haujlwm siab ntawm ABS resin. Lub amorphous xwm ntawm ABS resin thiab crystallinity ntawm PET nyob rau hauv no blend muab nws zoo mouldability, seem stability, tshuaj tsis kam thiab roj thiab tshav kub kuj.
Kev sib xyaw ntawm ABS nrog lwm cov polymers
Blending ABS nrog polyvinylidene fluoride (PVDF) txhim kho cov tshuaj tiv thaiv, puas ntsoog, kev ua qias tuaj thiab huab cua ntawm ABS. Kev sib xyaw nrog styrene / butadiene / styrene (SBS) copolymer tuaj yeem txhim kho qhov fluidity thiab qis-kub tsis kam ntawm ABS, thaum SBS yog 10%, lub ntsiab lus ntawm qhov sib tov yog -38 degree, thiab lwm yam kev hloov pauv tau zoo heev. me me, thiab nws cov khoom txhaj tshuaj molded ua tau raws li qhov yuav tsum tau ua ntawm cov khoom siv dej khov. Blended nrog polyphenylene sulfide (PSO) los yog CPE, lub tshav kub tsis kam thiab nplaim retardancy ntawm ABS tuaj yeem txhim kho.
ABS thiab polypropylene yog cov tshuab tsis sib xws, thiab cov khoom tensile thiab kev cuam tshuam ntawm kev sib xyaw ncaj qha tsis zoo dua li cov ntshiab polymers. Polypropylene thiab methyl methacrylate graft copolymer rau ABS / PP sib xyaw ua ke, tuaj yeem txhim kho cov khoom cuam tshuam, ntxiv 5 mus rau 10 feem ntawm vinyl acetate cov ntsiab lus ntawm 20% mus rau 40% ntawm EVA resin hauv ABS / PP blends, lossis ntxiv 5. mus rau 10 qhov chaw ntawm styrene - diolefin thaiv copolymer (butadiene cov ntsiab lus ntawm 40% mus rau 70%) hauv ABS / PP sib xyaw, cov polymer muaj cov tshuaj tiv thaiv zoo. Cov polymers muaj cov tshuaj tiv thaiv zoo.
